摘　　要：目的探讨后牙区螺丝固位与黏结固位种植固定义齿临床修复效果的差异。方法选择上下颌后牙区牙列缺损患者42例共70枚种植体,其中24枚采用螺丝固位修复体,46枚采用黏结固位修复体。分别于修复后1年复诊,检测种植体周围边缘骨吸收量、改良菌斑指数(mPLI)、改良出血指数(mSBI)等临床指标以及患者对种植义齿的美观满意度。结果螺丝固位组及黏结固位组平均种植体周围边缘骨吸收量分别为0.78mm和0.68mm;螺丝组与黏结组mPLI平均水平P50均为1,mSBI平均水平P50亦均为1;两组美观满意度平均得分P50为1。统计结果显示螺丝固位组与黏结固位组间种植体周围边缘骨吸收量、mPLI、mSBI以及患者满意度的差异均无统计学意义(P>0.05)。结论后牙区螺丝固位与黏结固位种植义齿短期临床修复效果差异无统计学意义。Objectives The purpose of this clinical study was to compare the short-term prosthetic outcomes of screw- and cement-retained implant-supported restorations after 1 year follow-up. Methods A total of 70 dental implants were placed in the posterior regions of 42 partially edentulous patients. 24 crowns were screw-retained, while 46 crowns were cement-retained. Peri-implant marginal bone level, modified plaque index （mPLI）, modified sulcus bleeding index （mSBI） and esthetic fulfillment were recorded at the 12 months recall after implant loading. Results The mean peri-implant marginal bone lost in screw-retained group and cement-retained group were 0.78 mm and 0.68 mm, respectively. The median values of mPLI and mSBI were both 1 in screw-retained group, and also 1 in cementretained group. The median scores of esthetic fulfillment were both 1 in screw-retained and cementretained group. The differences of marginal bone resorption, peri-implant soft tissue condition and patient satisfaction between two groups were statistically not signifieant （P 〉 0.05）. Conclusions The short-term clinical outcomes of implant restorations are satisfactory, either screw-retained or cementretained. The retention patterns seem to have few influences on the prosthetic outcomes of implantsupported restorations.
